Speed warning 2*
Storing warning 2 is recommended if you al­
ways
want to be reminded of a certa in speed,
for examp le when you a re traveling in a coun­
try that has a general maximum speed limit,
or if you do not want to ex ceed a spec ified
speed for winter tires.
The . (USA models) /. (Canada mode ls)
speed warning 2 symbo l appears in the dis­

258 Tires and wheels
Accordingly, when the low tire pressure tell­
tale illuminates, you should stop and check
your tires as soon as possible, and inf late
them to the proper pressure. Driving on a sig­ nificantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-in­
flation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's han­
dling and stopp ing ability.
Please note that the TPMS is not a subst itute
for proper tire maintenance, and it is the driv­
er's responsib ility to ma inta in correct tire
pressu re, even if under- inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale . When the sys­
tem detects a malfunction, the te lltale will
f lash for approximately one minute and then
remain cont inuous ly illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction ex ists .
When the malfunct ion indicator is illuminat­
ed, the system may not be able to detect or
signal low t ire pressure as intended. TPMS
malfunctions may occur for a variety of rea­
sons, includ ing the installat ion of replace­
ment or a lternate tires or whee ls on the veh i­
cle that prevent the TPMS from functioning
p rop erly. Always check the TPM S malf unct ion
tellta le after replacing one o r more t ires or
wheels on your vehicle to ensure that the re­ p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly. Tire pressure indicator appears
App lies to vehicles : wi th tire p ress ure mo nito rin g system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction .
Fig. 194 Display: u nde rinfla tion warning
Using the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum­
ference and vibration characteristics of the in­
dividua l tires.
If the pressure decreases in one
or more t ires, this is indicated in the instru­
ment cluster with a
RI] war ning symbol and a
message¢
fig . 194 . The driver message in the
display goes out afte r 5 seconds . The driver
message can be displayed again by pressing
the
ISETI button. If o nly one tire is affec ted,
the display will ind icate its position.
The tire pressure monitoring system must be
reset via rad io or MMI* each time the pres­
sures are adjusted (e.g. when switching be­
tween partial and full load pressure) or after
changing or replacing a tire on your ve hicle
¢
page 259. The TPMS indicator only moni ­
tors the tire pressure that you have previous ly
stored. You can find the recommended tire
pressures for your vehicle on the label on driv­
er's side 8-pillar ¢
page 234.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the tire pressure in one or more tires is too
low,
- the tir e has structural damage,
- the tir e pressure was changed, wheels rotat-
ed or rep laced but the TPMS was not reset

page 259. If the indi­
cator light does not turn off or if it turns on
shortly thereafter, immediately drive your ve­
h icle to an authorized Audi dealer or author­
ized repair facility to have the malfunction
corrected.
.&, WARNING
- If the t ire pressure indicator appears in
the instrument cl uster d isplay, one or
more o f your tires is significantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the t ires and the ir pressures. In­
flate the tire pressure to the proper pres­
sure as indicated on the vehicle 's t ire
pressure label~
page 234 . Driving on a
significantly under-inflated tire ca uses
the tire to overhea t and can lead to tire
failure. Under-inflation also is likely to impair the vehicle 's handling and stop ­
ping ability.
- The driver is responsible for mainta ining
the correct tire pressures. You must check the tire pressures regularly .
- Under certain cond itions (such as a spor ­
ty driving style, winter conditions or un­ paved roads), the pressure monitor indi­
cator may be de layed .
Tire s an d wheel s 259
-Ask your a uthorized Audi dea ler if run­
flat tires may be used on your vehicle.
(D Tips
- The tire pressure mon itoring system may
stop working when there is an ESC ma l­
function.
- Using snow chains may res ult in a system
ma lfunction.
- The tire pressure mon itor ing system on
your Audi was deve loped using tires with
the "AO" or "RO" identification on the
tire s idewall
~ page 248. We recom­
mend us ing these tires.
Reset tire pressure monitoring system
App lies to vehicles: with tire pressure mon itor ing system
If the tire pressure is adjusted, wheels ore ro­
tated or changed, the TPMS must be reset via
radio or MMI*.
... Before storing the new tire pressures, check
that the current pressures on all four tires
correspond to the specified va lues and
adapt the pressures to the current load
